Tumors can use both active and passive methods to enter the vasculature. [10] Some studies suggest that cancer cells actively move towards blood or lymphatic vessels in response to nutrient or chemokine gradients, [6] while others provide evidence for the hypothesis that metastasis in its early stages is more of a random behavior.
In TLS, the breakdown occurs after cytotoxic therapy or from cancers with high cell turnover and tumor proliferation rates. [4] The metabolic abnormalities seen in tumor lysis syndrome can ultimately result in serious complications such as acute uric acid nephropathy, acute kidney failure, seizures, cardiac arrhythmias, and death.

Although T- cells are powerful tools that help us defend against cancer through immune responses, errors may still occur during the process, and cancer's anti-tumour effect may vary. For example, the T- cells may not be activated and sustain the anti-tumor effect long enough, or the number of T-cells presented is insufficient.
There are several mechanisms that lead to escape of cancer cells to immune system, for example downregulation or loss of expression of classical MHC class I (HLA-A, HLA-B- HLA-C) [7] [4] which is essential for effective T cell-mediated immune response (appears in up to 90% of tumours [7]), development of cancer microenvironment which has ...
These cancer-fighting agents tend to hinder the growth of blood vessels that supply the tumour, rather than killing tumour cells directly. [35] They prevent the tumour from growing. For example, bevacizumab / aflibercept is a monoclonal antibody that specifically binds to vascular endothelial growth factor (VEGF), preventing VEGF from binding ...
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
The immune response to cancer can be categorized into the two main categories as discussed above: innate immunity and adaptive immunity. Innate immunity is the first line of defense against cancer. It consists of non-specific immune cells that can recognize and destroy abnormal cells, including cancer cells.
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
